On the more picky side, I'd limit the music played to mostly Manchester based bands, past and present.
'Right here, right now' when the teams come out. It's the intro that gets people in the mood. When they play it they skip to part way through the song. There should be no music 10 mins before kick off and then 'Right here, right now' from the beginning when the players are in the tunnel and about to come out.
The team announcing makes zero sense. They announce the team 10 minutes before kick off really slowly and then do it again 5 minutes later when the players come out. Just do it when the players are out and list the line up on the screen before that.
